We didn't do any bore holes before starting so the engineer's design was for concrete strip footings bearing on the soil about 600mm below ground level.

When they started digging it became obvious that just below this level, and covering the entire block, was weathered sandstone. So they dug a little deeper and then poured the concrete strip footings on rock.

This makes for an excellent foundation and hopefully I won't have any settlement issues. The only problem with the rock is digging under the driveway for the OSD tank is now going to be expensive !

Good luck with the build, cant wait until its finished, beers on Greg and I

......we lost the first 5 weeks of our build photos on a dodgy memory card.....back them up regularly. Tip - if you can take a photo every day from the same spot, strings together into a nice fast view album

Edit: Big if you're interested I can dig up some of our foundation photos if I can find em

I might have to jump on a plane to see this one when it's finished.
Have to decided on the audio for a room this size?

You're very welcome to come and visit and being from SA your price of entry will be a six pack of Coopers !

Speakers will be either Seaton or Procella ... both have plenty of output for this room. I'm losing about 1m at the front for baffle wall and screen wall, and about 1m at the rear for equipment, storage and some Erskine "secret sauce" !!

Peter - got plans yet from Dennis? even just a hint? or are you holding out on us?

Hi Peter,

I received my 95% drawings from Dennis ages ago, but I need to finalise speakers before he finishes them. I don't think I'll be posting Dennis' drawings but I will post my Sketchup model.

One idea I've got floating around in my head is to have the aesthetics reflect the acoustics ... the walls are being covered in fabric wrapped panels (no surprises there !) which run from column to column and are about 600mm high. There are three types of panels (absorber / diffuser / combo) which I'm thinking of doing in three shades of blue. Dennis' design has the three types arranged in what looks like an almost random pattern (but is obviously very carefully designed and laid out by him). For some strange reason I think it'd be cool to have the colour scheme match the purpose of each of the panels. I'll be putting this into Sketchup shortly to see how it looks !! Hopefully not hideous !!!

Thanks Peter I will certainly be up for that.
I might have to re-think the size of room I want Dennis to design for me down the track.
So your room will end up what I was wanting about 7.5m long.

Interesting idea with the fabric - what type of fabric are you using? I think it could look good. Depends how you're going to integrate it all i.e. the fabric and non fabric bits....I've struggled with this. Have you seen this thread? it might give you some ideas:

I had decided on the Seatons, but then I ran into Gerben at CEDIA here in Sydney and he's really after me to use his stuff. I will definitely make a decision in the next few weeks, as I need to get it all on order.

I haven't finalised the fabric yet but GOM FR701 is the obvious choice, and I understand you got yours from the US. I may go down this route as well.

Dennis has spec'd the Quest panels and I have a quote from the guys in Melbourne for all of them, however I may DIY the absorbers and diffusors. The combo panel is apparently not DIY'able.

Yes I had seen that thread ... some really nice stuff. Once I get my Sketchup stuff posted, I'll certainly be asking for more design ideas. Aesthetics is not my strong suit .. after all I'm an engineer !

Hey there Peter! Great to see some progress. I love the way Peter the Greek loads me up for beers without even asking!
That is going to be one impressive theatre. I couldn't help but look at the front and rear windows and think that council insisted they be there. Buggers like that. Even still, you are going to rattle around in that theatre with two rows of seating. I am sure Dennis has come up with something special for you.
Will be watching this Thread. Going to pilfer all your good ideas!
Cheers
Greg.
